Fill in balding areas

There are 96 quick hair growth products available in Australia today and we've tried them all. You know it, we know it, they make massive claims with dud results.

Sure they have impressive before and after photos - many of which have been stolen from OUR website. Yes, legal letters flying everywhere, what a waste of our energy. 

So that's why we decided to by-pass all the cr*p claims and focus on an invisible camouflage - that works. 


Read more/less

Shakes in, clings to what's there (no matter how fine or sparse) and makes the area look like it's got hair.

What could be more simple?

The before and after photos on our site were taken by our team, on some of us, and on our customers and relatives.

Whether you’re just starting to notice some thinning or you have a decent sized area of visible scalp, we’ve got you covered (pun intended).

Nut Job clings like a mofo. Slightly electrostatic little stage 5 clingers grip to your hair shafts in wind, while playing sport, at the gym, in ... bed.

No one can see you have filled in those spots. Not even close up. 

It's a simple shake on product. Shake it over the thinning area, pat it down a bit so the fibres go along the hair shaft, add spray for a bit of insurance (not 100% necessary but many of us do anyway). Then you are good to go.

Nut Job has revolutionised the hair fibre game. There are a few similar products on the market but they’re chock full of chemicals, made from animal products, turn green in the sun and can run down your face with sweat (Rudy Giuliani anybody?). 

Nut Job is a vegan product made from cotton, with minimal chemicals (in fact 0.00001mg per application), so your follicles remain healthy. It’s totally colourfast so you won’t have to check your reflection at every available opportunity.

Are you surrounded by guys with loads of hair? Looking at those TV personalities with heaps of hair and wondering why you? You are not alone! The vast majority are using hair fibres like Nut Job. We know because we supply them!

Even if you are holding out hope for a more expensive solution like surgery or medication, Nut Job is perfect to fill in the spaces in the meantime.

You get free shipping if you spend over $70 so get two! We know once you start using Nut job, you will want to continue. So - nothing to lose!

Once you've joined the thousands of Aussie guys using Nut Job, you'll want it reliably delivered. No problems you can ...

    Colour type is too light

    Dark brown is too light. It’s more like a medium-light brown. I have 2 full bottles I can’t use because they don’t match my dark brown hair.

    Works well but expensive

    Works as well as others without the burning on the scalp that l found by using other brands. I gave it 4 stars because it is more expensive than other brands.
